NOCS Zero Tube 10x25 Waterproof Monocular - Ultra Blue

The Zero Tube is our most advanced monocular—engineered for backcountry missions, fast movement, and demanding conditions. Featuring ED glass, dielectric-coated BaK4 prisms, and fully multi-coated lenses, it delivers exceptional resolution, contrast, and color accuracy in a form factor that all but disappears in your kit. This is precision optics for people who move light and look far.

Waterproof, fogproof, and built with a rugged, no-slip housing, the Zero Tube thrives in the alpine, on the water, and deep in the field. A built-in carry clip keeps it within reach, while its ultra-compact design makes it easy to forget—until you need it. When clarity, durability, and packability matter most, the Zero Tube is the one you bring.

• Extra-low dispersion (ED) glass sharpens resolution, improves contrast, and delivers more accurate color—so fine details stay crisp when you’re glassing terrain, wildlife, or distant lines.
• Premium BaK4 prisms with dielectric and phase coatings maximize light transmission and clarity, especially in low-light conditions when seeing clearly matters most.
• Rugged, impact-absorbing housing feels solid and natural in hand, with added grip to protect your binoculars when they inevitably take a hit along the way.
• Ultra-compact form factor at just 110 × 40 mm makes the Zero Tube the most packable high-performance monocular in its class—easy to carry, hard to leave behind.
• Waterproof (IPX7) means they’re built to handle storms, splashes, and full submersion up to 1 meter for 30 minutes—because weather rarely asks permission.
• Fogproof construction with nitrogen-filled chambers prevents internal fogging as temperatures and conditions change.
• Twist-up eyecup adjust easily for a comfortable fit, whether you’re wearing glasses or not.
• Integrated carry clip attaches securely to packs or belts for fast, one-handed access when the moment appears.
• No-Matter-What™ Lifetime Warranty backs every pair, so you can roam farther, use them harder, and worry less about the rest.
